A slip ring is secured to the coil housing, and a spring-loaded brush means is secured to the compressor for sliding engagement with the slip ring.  A clutch rotor is secured to an end of the inner coil housing wall adjacent the armature plate and extends radially outwardly from said inner wall so as to provide an uninterrupted circular air space with the outer coil housing wall adjacent the armature plate, such that no shorting of the lines of flux can occur from the end portion of the outer wall to the clutch rotor, providing a faster and stronger attraction of the armature plate when the electromagnetic coil is energized.

Abstract: METHOD OF CONTROLLING CRUSHING PLANT     ABSTRACT OF THE DISCLOSURE                   For control of a crushing plant to ensure both that a quota quantity of product is produced during each working period and that the product has optimum economic value by reason of small particle size, determination is made of the amount of product passed through the plant from the beginning of the period to each of a number of measurement times during the period. Each such determina-tion gives a "still to go" quantity, hence a theoretical new feed rate to be maintained.  The rate of feed of material into the plant is adjusted in correspondence with the ratio between that theoretical rate and the actual feed rate prevailing during an interval just before the measurement time. The crushing mechanism is controlled constantly to draw the full power available to it while it maintains output substantially in step with prevailing feed rate, such control being effected by adjusting crusher setting, apportioning feed material between crushers and/or controlling the relative portions of output material from a crusher that are respectively recirculated through that crusher and transferred elsewhere.

Abstract: ABSTRACT A method and an apparatus for indicating the size distribution of particles in a flowing medium are disclosed.  The medium is lit with a light that is perpendicular to the flow direction and has a substantially constant intensity, and a fixed duration.  The light passing through the medium is converted to an electric signal that varies with the light intensity.          A number of measuring devices are employed, each having a light source, detector and optics therebetween.  The different devices have different resolutions and detector fields of vision.  All of the devices are used on a medium to be tested and the readings from all, in conjunction with sen-sitivity coefficients of the devices to different particle size portions, yield the particle size distribution.

Abstract: Case 3351 RADIAL LEAD THERMAL CUT-OFF DEVICE            Abstract of the Disclosure A radial lead thermal cut-off device for opening an electrical circuit when a predetermined temperature is disclosed. Electrical connection between the radial leads is maintained by thin spring contact which is forced against the terminal heads of the leads of the device.          The spring contact is forced into contact by a disc against the force of a coiled bias spring that engages the center of the spring contact.          The disc is held in place by a temperature-sensing pellet of organic material which melts at a predetermined temperature and which preferably incorporates a multitude of spherical glass beadsfilling that greatly increase its strength. The pellet has a centrally located cavity so that when the organic material of the pellet melts the material fills a volume having a smaller transverse dimension. This allows the disc to move as the compression force of the coiled spring is relieved, which in turn opens the circuit between the contact members as the thin spring contact is forced away from the lead heads by the coiled spring.

The invention also relates to a novel arrangement of drive rollers, support rollers and casters cooperating with one another and with the various mechanisms for applying the solvent and removing same that both guide the unit and insure treatment of the lane all the way from the foul line to the pin deck. In addition, the invention encompasses a control system including lane position sensing mechanisms which govern the movements of the stripper as well as its operating cycle.

Abstract: ABSTRACT A fuel Metering system for a two-cycle internal combustion engine comprises an induction pipe through which air is drawn and mixes with fuel entering through an injection orifice in the pipe.  A diaphragm pump has a diaphragm separating first and second pump chambers, the first chamber being in communication with the crankcase of the engine and the second chamber being connected through a one-way valve to a fuel tank and through a pressure valve to the injection orifice in the induction pipe.  The one-way valve and the pressure valve are adapted to permit fuel to pass from the tank to the pump and from the pump to the injection orifice, respectively.  The system provides a simple method of metering fuel which is less complex than conventional carburettor and fuel injection systems and also eliminates the use of a float chamber which renders the system particularly suited to mobile applications such as chain saws, etc.

Abstract: TRANSMISSION LINE FILTER                Inventor;  Robert G. Geissler ABSTRACT OF THE DISCLOSURE:    A transmission line filter having two conductors with insulation therebetween.  A third conductor of a length related to the wavelength of the signal being filtered is spaced from one of the conductors but electrically coupled thereto.  Terminal connectors are located at each end of the filter to interconnect the filter into the regular transmission line of the system in which the filter is being used.  The filter can be formed of coaxial cable and can be a single frequency filter, a multiple frequency filter or a bandpass filter arrangement.          In a filter trap arrangement, one end of the third conductor is conductively connected to the other of the main conductors.          A method for making a coaxial embodiment of the filter is achieved by initially placing the main line inner conductor together with the third conductor within the dielectric and subsequently chopping out sections of the third conductor line to adjust its length to the wavelength of the signal being filtered and to provide electrical connection to the outer shield which is subsequently placed over the dielectric.  The filter provides unique application in controlling programs sent to subscribers in cable TV systems.    The aforementioned Abstract is neither intended to define the invention of the application which, of course, is measured by the Claims nor is it intended to be limiting as to the scope of the invention in any way.
